Identity document authentication

Abstract

A device implementing a system for authenticating an identity document includes at least one processor configured to receive, from a service provider, a request associated with verifying an integrity of an identity document, and capture, responsive to receiving the request, image data of the identity document. The at least one processor is further configured to generate a representation based on the image data, the representation comprising form factor data of the identity document, and compare the representation with a prior representation of the identity document, the prior representation comprising prior form factor data of the identity document. The at least one processor is further configured to provide, to the service provider, a response to the request based on comparing the representation with the prior representation.

What is claimed is: 
     
       1. A method, comprising:
 providing, to an identity provider, a request to authenticate an identity document, the request comprising prior captured image data of the identity document; 
 receiving, from the identity provider, an indication that the identity document has been authenticated based on the prior captured image data; 
 generating, responsive to receiving the indication, a prior representation of the identity document based on the prior captured image data; 
 storing the prior representation; 
 receiving, from a service provider and after the storing, a request associated with verifying an integrity of the identity document; 
 capturing, responsive to receiving the request, image data of the identity document; 
 generating a representation based on the image data, the representation comprising form factor data of the identity document; 
 comparing the representation with the prior representation of the identity document, the prior representation comprising prior form factor data of the identity document; and 
 providing, to the service provider, a response to the request based on comparing the representation with the prior representation. 
 
     
     
       2. The method of  claim 1 , wherein the storing comprises storing the prior representation in a secure processor of a device. 
     
     
       3. The method of  claim 1 , wherein the form factor data indicates a position of a common security feature of the identity document relative to a specific feature of the identity document. 
     
     
       4. The method of  claim 1 , wherein the image data comprises RGB image data, and the form factor data is based on the RGB image data. 
     
     
       5. The method of  claim 1 , wherein the image data comprises infrared image data, and the form factor data is based on the infrared image data. 
     
     
       6. The method of  claim 1 , wherein the identity provider corresponds to an organization for issuing identity documents corresponding to the identity document. 
     
     
       7. The method of  claim 1 , wherein the indication that the identity document has been authenticated comprises a signed verification that is tied to a device by a public key of a public-private key pair, a private key of which is stored on the device. 
     
     
       8. The method of  claim 1 , wherein the service provider corresponds to an on-line merchant. 
     
     
       9. The method of  claim 1 , wherein the representation and the prior representation do not indicate personally identifiable information. 
     
     
       10. A device, comprising:
 at least one processor; and 
 a memory including instructions that, when executed by the at least one processor, cause the at least one processor to:
 provide, to an identity provider, a request to authenticate an identity document, the request comprising prior captured image data of the identity document; 
 receive, from the identity provider, an indication that the identity document has been authenticated based on the prior captured image data; 
 generate, responsive to receipt of the indication, a prior representation of the identity document based on the prior captured image data; and 
 store the prior representation; 
 receive, from a service provider and after the prior representation is stored, a request associated with verifying an integrity of the identity document; 
 capture, responsive to receiving the request, image data of the identity document; 
 generate a representation based on the image data, the representation comprising form factor data of the identity document; 
 compare the representation with a the representation of the identity document, the prior representation comprising prior form factor data of the identity document; and 
 provide, to the service provider, a response to the request based on comparing the representation with the prior representation. 
 
 
     
     
       11. The device of  claim 10 , wherein the storing comprises storing the prior representation in a secure processor of the device. 
     
     
       12. The device of  claim 10 , wherein the form factor data and the prior form factor data indicate a position of a common security feature of the identity document relative to a specific feature of the identity document. 
     
     
       13. The device of  claim 10 , wherein each of the image data and the prior image data comprises RGB image data, and
 wherein the form factor data and the prior form factor data are based on the respective RGB image data. 
 
     
     
       14. The device of  claim 10 , wherein each of the image data and the prior image data comprises infrared image data, and
 wherein the form factor data and the prior form factor data are based on the respective infrared image data. 
 
     
     
       15. The device of  claim 10 , wherein the identity provider corresponds to an organization for issuing identity documents corresponding to the identity document. 
     
     
       16. The device of  claim 10 , wherein the indication that the identity document has been authenticated comprises a signed verification that is tied to the device by a public key of a public-private key pair, a private key of which is stored on the device. 
     
     
       17. The device of  claim 10 , wherein the service provider corresponds to an on-line merchant. 
     
     
       18. The device of  claim 10 , wherein the representation and the prior representation do not indicate personally identifiable information. 
     
     
       19. A computer program product comprising code stored in a non-transitory computer-readable storage medium, the code comprising:
 code to provide, to a first service, a request to authenticate an identity document, the request comprising first captured image data of the identity document; 
 code to receive, from the first service, an indication that the identity document has been authenticated based on the first captured image data; 
 code to generate, responsive to receiving the indication, a first representation based on the first captured image data; 
 code to store the first representation; 
 code to receive, from a second service and after the first representation is stored, a request associated with verifying an integrity of the identity document; 
 code to, responsive to the request,
 capture second image data of the identity document, 
 generate a second representation based on the second captured image data; 
 
 code to compare the second representation with the first representation of the identity document, the first representation comprising first form factor data of the identity document; and 
 code to provide, to the second service, a response to the request based on the compare of the first and second representations. 
 
     
     
       20. The computer program product of  claim 19 , wherein the first and second representations do not indicate personally identifiable information.
